HLS-LL Disconnecting Streams After a Few Seconds

Wowza Streaming Engine
1

Hello,

I recently configured the new Wowza Streaming Engine server as per the HLS-LL instructions but the playback stops after a few seconds.
There are some interesting “destroy stream” and “disconnect” messages in the logs:

Welcome to the forums @Avi_Kaneti!

Sorry you’re having problems here with LL-HLS. This is a fairly new protocol and as a friendly reminder since you’re new, forums are not an official source of Wowza technical support, so for any streaming code review requests or potential bugs, we will need a ticket.

Please do submit one because customer feedback is really important to us so we can make sure the LL-HLS workflow is functioning properly. You can make some adjustments to the segment size and lower your bitrates as a test to see if that helps.

Here is where you can submit a ticket so we can test it and see what is wrong:
